Re: Issue with GDB under Cygwin and XP
I compiled the latest gcc and gdb and it now works under cygwin.
The versions I'm using are:

I ran GDB on a simple C program and captured the output (below).
I have a few questions:
Why can I run the program several times with no errors but as soon as I
set a breakpoint at main it gets a SIGSEGV fault?
Why does the backtrace show only addresses?

You could also use the mailer support for retrieving messages but would be harder I guess.

Works fine on my Windows XP Pro machine using the same GDB and gcc
version 3.4.4. What gcc version do you have?
The stack trace would indicate that the crash is occurring before it
gets to your main function, since that code doesn't have debug symbols
you get addresses.
Jim,
It's definitely crashing before getting to main and I don't know why.
The tools versions are: gcc 4.2.3, binutils 2.17.50, and gdb 6.5.50.

Actually I was incorrect. The dump I gave you was for gcc 3.4.4.
I got it to run under gcc 4.2.3 using Insight.
I modified the program as follows:
/*
Name: HelloWorld.c
Author : Ray Hurst
Version :
Copyright : Your copyright notice
Description : Hello World in C, Ansi-style
*/
#include stdio.h
#include stdlib.h
int main(void) {
int a,b,c;
a = 10;
b = 20;
c = 30;
puts(!!!Hello World!!!); /* prints !!!Hello World!!! */
printf(\na = %d, b = %d, c = %d\n, a,b,c);
return EXIT_SUCCESS;
}
When I step through the program I cannot get the Local Variables window
to update the variables when I step over the lines setting the variable.
I look at the stack area in memory they definitely are updating.

Local variables window? Is that in insight? I've not used insight so
can't really help you there.
